EFTS 2021 – European Frequency and Time Seminar

The EFTS is a no-profit intensive full-week seminar intended to provide education and training with lectures and lab sessions. It targets the broadest audience: Engineers, Ph.D. students, post-docs, young scientists, newcomers, etc.
This seminar is unique in the following:

  • Broad spectrum of topics related to time and frequency
  • Balance between academic and applied issues
  • Broad target audience, yet keeping high level education
  • Lab sessions. The participants work themselves in small groups with a wide range of instruments made available.

The high level of training is guaranteed by the world-class Scientific Council and lecturers from the major European and International Institution.

NASA Workshop Announcement: High Performance Clocks in Space for Fundamental Physics/Science

The Biological and Physical Sciences (BPS) Division of NASA’s Science Mission Directorate (SMD) will hold a workshop on June 17, 2021, at 8-11 am Pacific Time (15-18 UTC) with two principal goals: (i) seeking community input on possible future missions focused on precision measurements/tests of fundamental physics using high performance clocks in space and (ii) organizing the preparation of white papers in response to the upcoming Call from the Decadal Survey Committee. Central to the discussion will be a recent mission concept (Fundamental physics with an Optical Clock Orbiting in Space) that proposes to place an optical clock in an elliptical orbit to test General Relativity, but all types of clocks-in-space-based fundamental physics research are encouraged (gravitational wave detection, dark matter searches, drifts of fundamental constants, etc.). Also encouraged will be the development of essential supporting technologies including time transfer, optical clocks, and space-qualifiable lasers.

The Workshop will begin with several brief presentations on science possibilities for optical clocks in space with generous time allotted for follow-up questions and discussions. We will conclude this first session with a presentation on the FOCOS mission concept followed by discussion. Following a short overview on the white paper process, we will then have break-out sessions focused on organizing authors and topics for potential white paper submissions. NASA/JPL scientists will be on hand to answer questions.

Attendees are encouraged to register one week in advance and submit one PowerPoint slide describing their white paper focus interests, which they will be able to present during the break-out sessions. The slides will be used to help organize the break-out sessions around the topics of greatest interest to the attendees and to jump start the white paper process.

Expected Workshop output: We hope the workshop will help to generate many interesting and high quality white paper submissions in the space clock science area as well as to identify potential lead authors for various topic areas.

Workshop “Optical Clock Comparison using VLBI” – will be held virtually

The workshop aims at discussing  advanced clock comparison using VLBI with the support of advanced GNSS techniques and fiber links, and is organised by the Italian and Korean NMIs (INRIM and KRISS), the Italian Institute of Astrophysics (INAF), the Korea Astronomy and Space Science Institute (KASI), the Korea Institute of Science and Technology Information (KISTI) and the Korea Advanced Institute of Science and Technology (KAIST).

It includes both invited sessions upon general aspects & advances in the field of optical clocks, VLBI technologies and international clock comparisons, followed by more technical sessions specifically dedicated to the design of a VLBI clock comparison campaign between Italy and Korea.
A program can be found at https://sites.google.com/view/occ-vlbi, where more info will be posted soon.

We kindly ask you to fill the registration form below by May 27th, 2021. The meeting links will be sent out to registered participants before the workshop.
